Personal Biography：

Dr. Tang graduated from National Tsing Hua University in Taiwan, majoring in Chemical Engineering. Currently he is the manager of the Resin and Coatings Laboratory of the Taiwan Industrial Technology Research Institute (ITRI), which has more than 6000 employees and is affiliated to the Taiwan government. There are 28 researchers in Dr. Tang’s laboratory. The topics they focus on include anti-corrosion coatings, water-based coatings, acrylic resins, polyurethane resins, and epoxy resins…etc. They were experienced to incorporate the nanotechnology, biomass raw materials, and organic/inorganic technology and other means to assist the coatings and resin industries in developing new products. Also, their inventions are kept in line with the megatrend and Taiwan government’s policies, such as low VOC, low carbon footprint, renewable energy, high-value petrochemicals…etc.

Presentation title：
Development of Bio-based Acrylic/Polyester Resin:

This presentation will introduce ITRI’s breakthroughs in bio-based resins, focusing on the impact of using bio-material sources and how we address them. In recent years, with the rise of environmental awareness and in response to the 2050 net-zero carbon emission goals, ITRI is also seeking solutions that align with environmental protection and performance of resins. Apart from switching solvents to water or increasing its solid content, the depletion of natural and fossil resources has prompted us to develop resins from renewable sources to achieve carbon reduction goals.
However, blindly using bio/recycled materials to prepare resins typically does not yield the desired properties. On the one hand, while we synthesize bio-based emulsion, because of insufficient reactivity of the bio-based monomers, we understood the amount of reactive monomer (methyl methacrylate, MMA) is a crucial factor for bio-based emulsion synthesis. On the other hand, according to previous experiences, introducing bio-based materials to the polymer chain will reduce properties. In response to this issue, we introduce multi-functional group structures to the polymer chain, leading to subsequent prepared coatings achieving both good perfomance and high bio-based materials content.
In conclusion, through the appropriate sorting of bio-monomers and resin structure design, we have developed high bio-based content acrylic emulsion (bio-based content exceeding 50%) and the bio-based polyester coatings exhibit good adhesion and weather-resistance on metal substrates.
